Nu ViB3 Nest with Cowbird Egg in Hemlock Tree. Ithaca. (May

This cowbird egg was kept from hatching by a floor built over 

 it by the vireo. 



Nu ViB4 Nest on Hemlock Twig, and Young Cowbird. Ithaca. 

 (June 16, 1914) Allen 



This is the same nest as shown in Nu ViB3. After the floor 

 was built three vireo and two cowbird eggs were laid in the nest. 

 This young cowbird is the sole survivor. 



Nu ViB6 Adult in Nest in Hemlock Tree, a Man's Hand Almost 

 Touching It. Ithaca. (May 19, 1913) Allen 



The bird knew no fear while incubating, so that one could pull 

 down the branch and stroke the bird. 



Vireo, Red-eyed (Vireosylva olivacea) 



The commonest of the vireos of New York, uniformly dis- 

 tributed. It is arboreal in habit. It sings from the tree top 

 throughout the day. 6-6.25 



Nu ViR Adult Repairing Nest into Which an Egg Has Been Laid. 

 Renwick, near Ithaca. (June 1910) Allen 



The nest is supported largely by cobwebs. The material of 

 which it is made becomes loosened as incubation advances and 

 the nest frequently has to be repaired continuously. 



Nu ViR2 Nest with Three Vireo Eggs on Top of Two Cowbird 

 Eggs 



Notice the manner of weaving the nest and also its position. 

 The nest is regularly suspended from a forked twig in a bush or 

 low limbed tree. 



For picture of nest with cowbird in it, see Nu Co44.
